Protective Equipotential Bonding

main equipotential bonding to be carried out, however its importance is often underestimated. The effect of applying main protective equipotential bonding is most noticeable in TT systems. Consider Figure 1 below (extract from IET GN 5). The touch voltage in the event of a fault with main protective bonding installed is given by: U t = I f (R 2)

Power Factor Correction - BS 7671 Home of the Wiring ...

A load with a power factor of, say, 0.8, results in much higher losses in the supply system and a higher bill for the consumer. A comparatively small improvement in power factor can bring about a significant reduction in losses since losses are proportional to the square of the current. When the power factor is less than one the ‘missing’
